django template language is not the same as jinja2

Question

i'm new in Django. i'm really curious to Django template language. i have used jinja2 before Django template language. Some people says that jinja2 and Django template language are the same. But i stuck on if statement on Django template language. usually when we are comparing some value to "True" we are usually not using "==" :

{% if somevalue %}
.....
{% endif %}

instead of....

{% if somevalue == true %}
.....
{% endif %}

i can't do the first method... why ???
